Create explosions

Low priority, but nice to have for future.

I think that good start for this could be refactoring of Arena.

I would like to see add_object method instead of add_robot, add_bullet and whatever else will come later. Then we can use just update_objects instead of update_bullets, update_robots...

The only issue which I do not know solve yet, is how to implement robots and bullets method. I can search all objects for objects with class Robot, but then I introduce coupling and add new knowledge to Arena class (it needs to know class of robots, bullets...).

Unfortunately I do not have any experiences if this is good solution or not. So if anyone can advice me then it would be really great! Thanks.

Maybe I am just over thinking this, but well... I want to have beautiful and good designed code ;)
